This invention relates to a portable conduit gripper which can be easily moved from place to place by the workman as required, and which is effective to grip a pipe or conduit so that the conduit may be cut into appropriate lengths.

My invention is particularly applicable in the electrical industry, and especially to artisans laying electrical conduits, structures, and where the wires must be placed in a conduit.

An object of my invention is to provide a novel portable conduit gripper which will engage a structural member in a building and simultaneously grip the conduit, these gripping operations being obtained by pressure on a single handle.

Another object of my invention is to provide a novel portable conduit gripper which is pro vided with two sets of jaws, one set of jaws engaging a pipe or conduit, and the other set of jaws engaging a fixed member, such as a structural piece in a building.

Still another object is to provide a novel portable conduit gripper which is simple in construction, inexpensive to manufacture, and effective in operation.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing:

Figure 1 is a perspective view of my conduit gripper.

Figure 2 is a fragmentary perspective view of the same.

Figure 3 is a fragmentary side view of the same.

Referring more particularly to the drawing, the numeral I, indicates a handle of suitable length, and formed of a suitable material. A gripping jaw 2, is formed on the upper end of the handle I, and this jaw is integrally formed with the handle. A second jaw 3, cooperates. with the jaw 2, to grip and hold the conduit 4, as will be further described. The jaw 3, is pivotly attached to the handle I, by means of the bolt 5. A spur 6, is integrally formed with the jaw 3, and is positioned below the pivot at 5, and is arranged alongside of the handle I, substantially as shown. This spur engages and grips a suitable stationary member, such as the studding or fioor joist 'I, of a building.

The studding or floor joist is formed of wood, and is usually 2 x 4, or 4 x 4, in dimension. A finger 8, is also pivotly attached to the bolt 5, and is preferably arranged between the handle I, and the spur 6. The finger 8, is formed with a spike 9, which also engages the studding I, opposite the spur 6. In operation the spur G, and spike 9, are placed on each side of a stud or floor joist l. The conduit 4, is now placed between the jaws 2 and 3. Downward pressure on the handle I, by the workman will now grip the conduit 4, and simultaneously will press the spur 6, and spike 9, into the stud or joist, thus holding the gripper in position, and simultaneously securely holding the conduit 4, so that this conduit may be sawed or otherwise cut into appropriate lengths. When pressure is released on the handle I, the conduit 4, can be removed and the spur E, and spike 9, will disengage the stud or joist.

In operation, my portable conduit gripper is first positioned on the studding or fioor joist with the spike 9 of the finger 8 and the spur 6 in position to be pressed into the wood. When the conduit is placed between the jaws: 2 and 3, and when pressure is applied to the handle i, the jaws 2 and 3 will grip the conduit and pressure on this conduit will be transmitted to the spur 6 and the finger 8, thus pressing the spur and the spike 9 into the wood to hold the tool in position. Thus, the use of the finger 8 is exactly the same as in a peavey or cant hook.

Having described my invention, I claim:

1. A portable conduit gripper comprising a handle, a jaw formed on one end of said handle,

a second jaw pivotally mounted on said handle and arranged opposite said first named jaw to grip a conduit, an integral spur extending from said second jaw, opposite to the conduit gripping end of said second jaw, and a finger having a spike thereon, said finger being pivotally mounted on the pivot for the second jaw and being located between the handle and said second jaw, said pivot consisting of a bolt extending through said handle, finger, and second jaw, said spike cooperating with the spur to engage a fixed member and support the gripper.

2. A portable conduit gripper comprising an elongated handle, a jaw integrally formed on one end of said handle, a second jaw pivotally mounted on said handle and arranged opposite said first named jaw to grip a conduit, an integral spur extending from said second jaw in. a direction opposite to the conduit gripping end of said second jaw, a finger, a spike integrally formed on one end of the finger, said finger being pivotally mounted on the pivot in the second jaw, said pivot consisting of a bolt extending through said handle, finger and second jaw, said spike cooperating with the spur to engage a fixed member and support the gripper.
